Looking to buy a 7.62 CQB platform

Re: Looking to buy a 7.62 CQB platform

if for home defense I recommend a 1919A4 on a tripod pointing at your bedroom door. Belt up as much defense as you'd like. That OR go with an AR with a good loading as mentioned

Thanks for all your input, I take all comments seriously. You never know when someones advice may save your life. At this point I am not looking to use the rifle for home defense, that is my I keep my Springfield .45 (230gr Federal HST)next to the bed and my 870 (00 buck) in the closet. I think I am going to look into building an Armalite 16" upper and using my existing lower. Thanks Again for all your input.

no i completely agree and some tier 1 assets are seriously pushing for the new 300 blackout wether then will ever trickle down who knows. they also have the mp7 too and i have yet to see that, lol. we will stick to 5.56 and 7.62 for the foreseeable future simply due to the unbelievable number of rounds we still have for those two calibers. why we EVER went to 5.56 is beyond me but thats a whole diferent story. </div></div>

Ok, I'm looking around, and I'm not totally sure, but what exactly is the difference between .300 Blackout and .300 Whisper? Is it just the 1mm difference in overall length? I see some difference in the ballistics, but I apparently don't know enough.

<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: Little Joe</div><div class="ubbcode-body">5.56 isn't and never was a very good CQB round if you think it is i'm sorry i do not. the package we are given isn't bad and it carries a lot of rounds but i've seen guys take several rounds center mass and run out of a room. If i could carry something else i would, i wish we had 6.8 that round is BAD ass as a SBR. </div></div>

ament to this....

the nice thing about the 6.8 is that it is designed for short set ups. Get yourself a 6.8 between 8-10inchs and call it a day.

Re: Looking to buy a 7.62 CQB platform


An option, Vector P51, This one has a reg sear so can be taken back to pistol config but SBR one and you can add stock, this one 100% reliable out of box. It IS hard hitting and 'decent' shooter to 200.

Re: Looking to buy a 7.62 CQB platform

Just because its a bigger caliber doesn't make it a better gun. Does it help? Hell yes it does, but you just might come across an incident where your firearm just doesn't seem effective.

For example Baton Rouge, Louisiana August 1, 1977. Field Training Officer Steve Chaney, and rookie Officer Linda Lawrence respond to a burglary call at an apartment in the Broadmoor Plantation. They encounter James Mullery (6ft, 200lbs) who is high on cocaine and PCP.
Senior Officer is armed with a S&W model 64 38special +P 125grain, and rookie Officer is armed with a similar weapon. Mullery attacks the officers and he receives 10 shots in the struggle (#1wrist, #2-3chest, #4left abdomen zero range, #5upper middle abdomen, #6top of head, #7-8chest, #9abdomen, and #10hip) before he dies of blood loss. Officer Linda Lawrence dies in the incident.

Does 5.56mm have a bad track record...yes, and I'll be switching mine ASAP. I have no experience with the LMT MWS or the others mentioned, but I do have the LMT monolithic CQB and its plenty light, and accurate to boot. Wonder it can be cambered in 300blackout? Anyway I think LMT would be pretty good choice IMO.

I wonder if that's the same incident I remember seeing a video reenactment of during one of Mas Ayoob's classes.

And I would think that you could set your CQB up for the .300 Blackout judging by the dimensions.

Re: Looking to buy a 7.62 CQB platform

For some reason I've always thought an H&K 53 re-chambered for .300 Whisper and fitter with a sound suppressor would just be more fun than a person should be able to have with their clothes on.

Re: Looking to buy a 7.62 CQB platform

Im not getting the yesteryear pistol anecdote as it relates to 5.56. Exactly where does this bad track record for 5.56 lie that you speak of?

Re: Looking to buy a 7.62 CQB platform

A member of my team just purchased a 7.5" 7.62x39 PWS Diablo upper for entry work. The 30rnd mags are a little long and only made by c-product. To start we had 3 out of 60 rounds fire and all kinds of jams. The upper was sent back with the mags and we were told the bolt had an issue and we got some of the older mags that they were having problems with. We will be getting the upper and mags back soon and will go out and give it another go. My hope is that it runs a hell of a lot better than it did the first time.

The reason for the 7.62x39 is that it is close to 6.8 in a sbr but a hell of alot cheaper. I like the thought of the 7.62 as it has better performance out of the short barrel but i get 5.56 for free. So it will depend on the performance of the upper when it comes back to see if i run the 7.62 or not.

I personally would like to run the 7.62 over the 5.56 hands down, but again if the system is not reliable then I'm not going through the door with it.

Just my .02

Re: Looking to buy a 7.62 CQB platform

Armalite is have a sale next week, I am going to see what sort of offers they will have on their 7.62 16" uppers. the upper that I am looking at is about $936. If anyone knows of a comparable or better product in that price range please let me know. I will be mounting it on my Armalite lower so it must match up properly. Also, where can I find short barrel 7.62 assemblies or just the barrels? I would like to find a 14" or so.

Re: Looking to buy a 7.62 CQB platform

nw1911guy its possible that its the same incident, and they did make a reenactment of it and use it for police training, but I've never seen it. I got it out of my ballistics book.
I would think it fits too, but what are the exact dimensions? My reloading manual says that the .223 case length is 1.760" and .378" in diameter. Blueprint would be nice to see.

Shane45 I can't particularly say from experience since I haven't seen combat, but talking to vets and hearing their experiences isn't exactly the most comforting information to hear. Maybe its bad shot placement? I've always wondered what happened to double taps to be honest.
From my brief study of anatomy I think the only thing guaranteed to stop a person is a shot to is the brain stem, and severing all communication to the body. Drugs-no drugs your still going down. Thats just my .02
Good shooting if you can pull off shot like that and I hope to rival your skills someday.

Re: Looking to buy a 7.62 CQB platform

Skyclad, my concern was that your data was mil scources. Unless you are in the military or otherwise bound by Geneva/Hague, it has little relevance for us. Dont let yourself get brainwashed by internet war stories that have little to do with our world. We are not restricted to ball ammo. In fact its my opinion if we just told the world to piss off and pass the ammo and gave our boys commercial ammo, we wouldnt even be having much discussion over 5.56 lethality. As I said earlier in this post, I would not feel at all undergunned with commercial performance 5.56 loadings with the possible exception of specialised penetration scenarios. So befoire you give up that mrp, consider your commercial ammo selections. I have seen AAR's on LE shootings with non ball ammo. It wasnt pretty for the shootee!

 

[Tengu]

Re: Looking to buy a 7.62 CQB platform

Thanks for the concern shane. Nah I'm not giving up on the 5.56 at all. In fact that is why I choose it. I considered my options for home defense, and I wanted a something that would be less likely to penetrate into the next house. If I have a problem with caliber a simple barrel change and a new bolt carrier and blame! 6.8spc coming at you, and just so you know I already have 12mags for it (5.56).
Honestly I'm a fan of shot placement if anything else. You can have all the firepower in the world, but if you can't put lead on target then what good is it?


Anyway good luck on your 7.62CQB rifle! Pics when your finished.

Re: Looking to buy a 7.62 CQB platform

Agree on shot placement.

This is the info I found and it's what I had figured. It's a .223 or .221 fireball necked up. Pretty much the same as the old .300 Whisper. AAC's website did mention some issues with the bullet ogive hitting a magazine rib in the case of the subsonic load and so they have a recommended OAL for the 220gr SubS.

http://300aacblackout.com/

Parent case----------.221 Fireball/.223 Rem
Bullet diameter------.308 in (7.8 mm)
Neck diameter-------0.334 in (8.5 mm)
Case length---------1.368 in (34.7 mm)
Overall length------2.10 max optimal / 2.26 max SAAMI

Re: Looking to buy a 7.62 CQB platform

Nice stick shane! LMT sexiness clothed in black. Planning on painting it? I put camo on my rifle and it came out looking pretty nice. I'll have to post pics sometime when I have oodles of time here at the shop....like now.

1911guy so does that mean I'll be able to fit these rounds in my Ar15 mags if I stay to optimal length? If so that saves me tons of money and effort on having to buy mags and new bolt.

 

[rsilvers]

Re: Looking to buy a 7.62 CQB platform

Yes, it works in normal AR15 mags and has the normal full capacity.

Re: Looking to buy a 7.62 CQB platform

Oh man now that is fucking cool! I was thinking about having a setup in 6.8spc, but the case diameter is .422" so that means new bolt carrier, mags, along with a new barrel. Ugh what a pain in the ass.
With the money saved I can just buy a new 100rnd mag instead. Thanks for the clarification. My investment is looking even sweeter

Arsenal-built AK47 or 74 gets my vote for a close quarter combat.
AK's stellar track record speaks for itself.
